Adopting the UNIX operating system platform and ARM11 low-power embedded/microcontroller architecture, the system runs quickly, stably and reliably, with an average time of no less than 100000 hours, and supports remote online upgrade and maintenance.
● Upstream communication interface: TCP/IP, 4G, WIFI and other communication methods
● Downstream communication interface: 5-channel MBUS interface, CJ/T 188-2004, MODBUS multiple protocol water meter access.
The M-BUS bus supplies power to terminal measuring instruments and collects measurement data, and can automatically cut off the bus power when meter reading is not required.
● It has data storage function, supporting timed freezing of data, classification and sub item storage, real-time reporting, and automatic saving during power outages.
● It has breakpoint resume function to ensure continuous, accurate and reliable data transmission. Network disconnection does not affect the accuracy of data transmission, ensuring the authenticity, smoothness and coherence of backend software data and graphics.
● It has real-time clock and automatic synchronization functions. The gateway is designed with a hardware clock, with a clock error of less than 0.5S/d. The backend server can remotely calibrate the gateway, and the gateway broadcasts the calibration of the measuring instruments.
● Ability to identify and transmit the operating status of measuring devices, self check and detect equipment (including communication) abnormalities, record and alarm functions;
Supports 5 isolated MBUS bus interfaces, each bus can connect 32~256 measuring devices, with a communication baud rate of 1200-115200bps (optional); All external interfaces are designed for isolation and lightning protection, ensuring safety and reliability.
